tion of Michigan Application December 11, 1931*.,y serial N0. 101,148 s claims'. (ci. 29e-4s) This invention relates to windows in motor vehicles and it has particular relation to anarrangement for slldably mounting the window so as to prevent rattling.

One object of the invention is to provide an improved window mounting which will constantly operate to eliminate rattles such as frequently are apparent, particularly after the motor vehicle has been in use for some time.

Another object of the invention is to provide an improved window mounting wherein means will be provided for preventing loose and rattling movement of the window in its own plane as well as transversely to such plane.

Another object of the invention is to provide an improved window mounting which efiiciently uses resiliently pressed rollers for avoiding rattling between the window and the guideways reciprocally guiding it in its movement.

Other objects of the invention will become apparent from the following description taken in conjunction with the drawings and from` the claims hereinafter set forth.

For a better understanding of the invention reference may be had to the accompanying drawings forming a part of the specification, wherein:

Figure 1 is a fragmentary view of a motor vehicle illustrating the manner in which a window is mounted vaccording to one form of the invention.

Fig. 2 is a fragmentary view on a. larger scale with certain `parts shown in cross section, of one side of the window mounting.

Fig.v 3 is a cross-sectional View taken substantially along the line 3-3 of Fig. 2.

Fig. 4 is a cross-sectional view on a larger scale taken substantially along the line 4-4 of Fig. 2.

Fig. 5 is a View similar to Fig. 2, but illustrating a diierent form of the invention.

Fig. 6 is a crossfsectional view taken substantially alongthe line 6-6 of Fig. 5.

Fig. 7 is a cross-sectional view on a larger scale taken substantially along line 1-1 of Fig. 5.

Referring to Fig. 1, the window is indicated at Iii, and a. metal channel receiving the lower edge of the window is indicated at I I. For reciprocating the window, slides I2 may be provided on the best by Fig. 4, and these guideways respectivelyA receive auxiliary channel members I8 that are somewhat smaller in size than the guideways I6 and which receive side edges of the window. For sealingthe space between the channel members against ingress of water or the like, resilient sealing strips 20 may be provided in small channel portions 2| formed in the free edge portions of the legs` or side walls of the guideways I6 and such sealing strips 'engage opposed legs of the channel members I8, respectively. The channel members I8 project below the window and for connecting them tothe channel member I I, metal bracket members 23 are interposed between opposite ends of the latter and the channel members IB and such bracket members may be welded as indicated at 24 tothe ends of the channel member II. 'Ihe bracket members include laterally directed lip portions 25 and 26 that project into the channel members I8 and which ar'e secured thereto by means of screws 28 and 29 re spectively. Thus, the window is supported on a frame comprising the channel member I I receivng its lower edge and the two side channel members I8 that are reciprocatory in the guideways I6. y

For preventing rattling between the auxiliary channel members I8 andthe guideways I6, in the plane of the window and transversely between the guideways, bell cranks 30 are pivotally mounted on the lower screws 29 as best shown by Fig. 3, and each of these bell cranks comprises similar spaced elements 3I and 32 of bell crank char acter, between which at one end of the bell crank a roller 33 is journaled. Intermediate their ends the bell crank elements 3| and 32 are journaled on a nut 34 into which the screw 29 is threaded and their opposite ends are connected to a tensioned spring 35 that in turn is connected to a lip 36 on the bracket 23. Adjacent the roller 33, the base portion of the auxiliary channel member I8 is recessed as indicated at 31 in Fig. 2, so as to permit the roller to project into rolling contact with the base portion of the guideway I6. Thus, at opposite edges of the window, the rollers 33 are resiliently pressed against the base portions of the guideways I6 at-all times so that rattling of the window transversely between the opposed guideways I6 is prevented.

For preventing rattling of the window transversely to its plane, a U- shaped bracket 40, best shown in Fig. 2 at 40, is'secured by screws 4I to the base portion of the auxiliary channel members I8 and between the base portion of this U- shaped member and the base portion of the auxiliary channel member, spaced plates 42 and 43 are provided which are pivotally mounted on a pin projecting between the base portion of the U-shaped member and the base portion of the auxiliary channel members. It may be added that a strengthening strip 46 may be disposed between the bracket 4 0 and the base portion of the auxiliary channel member I8. Between the plates 42 and 43 and also journaled on the pin 44, a roller 48 is provided and as best `shown by Fig. 3, this roller projects through an opening 50 formed in one leg of the channel I8 and so that it may have rolling contact with the adjacent leg of the guideway iii. The plates I2 and 417i also have a second roller iii journaled on a pin connecting the plates and this roller is adapted to project through an opening 53 in the opposite leg of the channel I6 so as to engage the opposite leg of the guideway i6. 'I'he plates 42 and it preferably comprise part of a bifurcated bracket connected by a web 54 as shown by Fig. 3, and a lip lili projects i'rom the plate and has a pin portion Sil secured thereto which receives a spring til that engages one leg of the channell. This yspring constantly urges the plates 42 and i3 about the pin 44, thereby maintaining both rollers t8 and 5I constantly in rolling contact with opposed legs of the guideway channel IB. The same construction, although inverted, is provided at a lower point as clearly shown by Fig. 3.

Referring now to Figs. 5, 6 and particularly to Fig. 7, the guideway I6 has its legs projecting beyond the sealing strips 20 to form guide portions 60 and 6I that terminate in outwardly di` rected flanges 62. The bracket member 23 in this case extends into the auxiliary channel I8 and is secured theretoy by bolts 63, and outwardly of the channel is provided with vertically spaced pressed in channel portions 64 having a base 65 and side walls 66. Within each of the channel portions, although disposed in relatively inverted positions, a roller supporting member 61 is disposed, which comprises spaced plate portions 68 and 69 connected at one end by an integral web 10 and at the other end of a curved socket portion 1I. A roller 12 is journaled on a pin 13 connecting the plate portions, and Aa second roller 14 is journaled on a pin 15 extending through the plate portions 'and also the side walls 66 of the bracket member 23. From this it will be seen that the member 61 may pivot about pin 15. The roller 12 is resiliently pressed against the guide portion 6I of the channel I6, by means of a spring 11 seated in the socket portion 1I and which abuts the base portion 65 of the channel portion 64 while roller 14 partially projects through a slot 18 in the base portion 65 and engages the guide portion 60 of the channel. It follows that the rollers will resiliently be pressed' against the guide portions 60 and 6I by using the spring 11 and pivotal action of the holding member 61.

One of the bell crank arms 30 is pivotally mounted on that portion of the bracket 23 projecting into the channel I 8 and it will be recalled that this bell crank has a roller 33 extending through a slot 31 in the base of this channel and which is resiliently pressed against the base of channel I6.

'Ihe arrangement of rollers described is provided at both sides of the window and it is apparent then that certain of the resiliently pressed rollers will prevent rattling and loose movement of the window in its own plane and that others will prevent rattling or loose movement of the window transversely to its plane.

The invention provides a simple and eillcient form of window and anti-rattling arrangement to avoid rattling constantly throughout the life of the motor vehicle. It is furthermore apparent that the rollers will not strongly resist movement of the window owing to the fact that they have rolling contact with the stationary channel guideway i6. The invention insures a smoothly and quietly working window and one which will avoid rattling which is so common in motor vehicles at the present time.

Although only two forms o! the invention have been described and illustrated in detail, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the appended claims.
